A rational expression that will be undefined at x=1?
Answers
[tex]r(x)= \dfrac{p(x)}{q(x)} [/tex]
will be undefined for the zeros of the expression [tex]q(x)[/tex]. For an expression with a zero equal to 1, the simplest way is to use [tex](x-1)[/tex] as a factor in [tex]q(x)[/tex]. In can be your only one, or you can mix in other factors.
But, so long as the denominator of [tex]r(x)[/tex] is equal to zero, as it is when [tex]q(x)=x-1[/tex], the expression will be undefined at that point x, because it would involve division by zero.

D. Initial value: 3, rate of change: 2
Answers
B. Initial value: 1, rate of change: 1
D is completely off. To get the initial value on a table you have to find the place where the input is zero.
So, you would take (2,3) and decrease both slots by 2 until x reaches zero. Now, we have (0,1). 1 is now our Initial Value.
To find the rate of change, you simply see how much the values increase/decrease. For example, let's take (6,7) and (8,9). As I said before, the input and output value increase by 2. Now, you put the change in 'y' over the change in 'x' and you have 2/2. After simplification, you are left with 1 as a whole number.

What is the midpoint of the segment whose endpoints are (-6,5) and (4,-7)?
Answers
(-6+4)/2=x
(-2)/2=x
-1=x
(5+-7)/2=y
(-2)/2=y
-1=y
To start, the formula to find the midpoint coordinate pair of two given coordinates is as follows:
([tex] \frac{x1+x2}{2} [/tex], [tex] \frac{y1+y2}{2} [/tex])
Knowing this, plug in your given values (the two x values are -6 and 4; the two y values are 5 and -7) and simplify:
([tex] \frac{-6+4}{2} [/tex], [tex] \frac{5+-7}{2} [/tex])
=([tex] \frac{-2}{2} [/tex], [tex] \frac{-2}{2} [/tex])
=(-1,-1)
Therefore, the midpoint of the coordinates (-6,5) and (4,-7) would be (-1,-1).

In an aptitude test if am given a question like this I wouldn't even solve it because the answer is in the question...
How???
"what is the common difference " then you asked" is it Arithmetic or geometric"
I would have chosen arithmetic because common difference is only typical to arithmetic progression... But this question is a typical Geometric sequence "we use Common ratio"
Common ratio = T₂/T₁
Common difference = T₂-T₁
T₂ = 12 and T₁ =-6
∴Common ratio = 12/-6 = -2......
Meaning each number in the sequence in creases by a factor of -2....
Multiply T₁ by -2 you'll have 12[T₂]

If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?
Please show how you did it!
Answers
Work
Step 1 - 37.5 x 0.8 = 30
Step 2 - 30 - 1.75 = 28.25
Step 3 - 28.25 divided by 2.5 = 11.3.
Step 4/ Final Answer - 11.3
take 2.5 of the number = 2.5x
when we add 1.75 - 2.5x + 1.75
and divide by 0.8 - (2.5x+ 1.75)/0.8
the answer is 37.5
lets construct an equation with this information
(2.5x + 1.75)/0.8 = 37.5
2.5x + 1.75 = 37.5* 0.8
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5
x = 11.3

A student earned grades of C, A, B, and A in four different courses. Those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. The grading system assigns quality points to letter grades as follows: A = 4, B = 3, C = 2, D = 1, and F = 0. Compute the grade point average (GPA) and round the result to two decimal places.
Answers
To compute the GPA, multiply each grade by its corresponding credit hours, sum up the grade points, and divide by the total number of credit hours. In this case, the GPA is 3.40.
Explanation:To compute the grade point average (GPA), we need to multiply each grade by its corresponding number of credit hours to get the grade points. Then, we sum up the grade points and divide by the total number of credit hours. Here are the calculations:
Course 1: C grade (2 grade points) x 4 credit hours = 8 grade pointsCourse 2: A grade (4 grade points) x 5 credit hours = 20 grade pointsCourse 3: B grade (3 grade points) x 1 credit hour = 3 grade pointsCourse 4: A grade (4 grade points) x 5 credit hours = 20 grade pointsTotal grade points = 8 + 20 + 3 + 20 = 51 grade points
Total credit hours = 4 + 5 + 1 + 5 = 15 credit hours
GPA = Total grade points / Total credit hours = 51 / 15 = 3.40

explain why the amount of propane in a grill’s tank and the time spent grilling could represent an inverse variation
Answers
The obvious answer is because propane is a gas at room temperature, while 2-propanol is a liquid at room temperature.
That happens because the intermolecular forces that exist between 2-propanol, or isopropyl alcohol, molecules are stronger than those that exist between propane molecules.
The amount of propane in a grill's tank and the time spent grilling represent an inverse variation. As the amount of propane in the tank decreases, the time spent grilling increases.
Explanation:In the context of a propane grill, the amount of propane in the grill's tank and the time spent grilling represent an inverse variation. In an inverse variation, as one variable increases, the other variable decreases, and vice versa. In this case, as the amount of propane in the tank decreases (more grilling time), the time spent grilling increases. This is because the more propane that is used up, the less time you have left to grill before running out of gas.

In a raffle, one ticket is randomly chosen from 80 tickets to receive free haircuts for a year. If Jake entered 6 tickets, what is the probability that he is not chosen to receive the free haircuts? Express your answer as a fraction in simplest form, percent, and decimal.
Answers
Final answer:
The probability that Jake is not chosen in the raffle is 37/40, 92.5%, or 0.925.
Explanation:
The question asks for the probability that Jake is not chosen to receive free haircuts for a year from a raffle of 80 tickets, where he entered 6 tickets.
First, we compute the probability that Jake is chosen, which is the number of tickets he entered divided by the total number of tickets, resulting in 6/80 or 3/40.
To find the probability that Jake is not chosen, we subtract this probability from 1 (the total probability space), yielding 1 - 3/40 = 37/40.
In the simplest form, this is already reduced. As a percent, this probability is 92.5%, and as a decimal, it is 0.925.

Four consecutive integer numbers add to 2. What are the numbers?
Let the smallest integer=x
The three consecutive integers will be x+1,x+2, x+3
Sum of four consecutive integers=2
So, x+x+1+x+2+x+3=2
Adding like terms, we get
4x+6=2
Subtract 6 from both sides
4x+6-6=2-6
4x+0=-4
4x=-4
To solve for x, let us divide by 4 on both sides
4/4x=-4/4
x=-1
So, the four consecutive integers are =x=-1
x+1=-1+1=0
x+2=-1+2=1
x+3=-1+3=2
So, the four consecutive integers are:= -1,0,1,2

A Web site defines a regular polygon as “a polygon with all sides the same length.” Is this definition valid?
A. Yes, because all regular polygons fit this definition.
B. Yes, because a square is a regular polygon.
C. No, because some polygons that are irregular fit this definition.
D. No, because not all regular polygons fit this definition.
Answers
Final answer:
The definition of a regular polygon as a polygon with all sides the same length is incomplete because it does not include the requirement that all angles must also be equal. Therefore, the best answer choice is C, as some polygons with equal sides do not have equal angles and are not regular.
Explanation:
The definition of a regular polygon as “a polygon with all sides the same length” is not entirely accurate, because it overlooks an important aspect of regular polygons. For a polygon to be considered regular, it must not only have all sides of equal length but also all angles must be equal. Therefore, the correct answer is C. No, because some polygons that are irregular fit this definition. For example, an equilateral triangle and a square are both regular polygons because they satisfy both conditions. However, a rhombus may have all sides of equal length but can have angles that are not equal, which makes it an irregular polygon.
